我们提出了一种简单的技术,用于从表面采样的点云的单速率压缩,基于点的生成树。与以前的方法不同,我们使用线性预测器和横向预测器来预测未来的顶点,线性预测器使用先前的边缘作为当前边缘的预测器,横向预测器将先前的边缘围绕估计的法线向左或向右旋转90°。
We present a simple technique for single‐rate compression of point clouds sampled from a surface, based on a spanning tree of the points. Unlike previous methods, we predict future vertices using both a linear predictor, which uses the previous edge as a predictor for the current edge, and lateral predictors that rotate the previous edge 90°left or right about an estimated normal.
